Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The shoulder blade; the most proximal bone of the thoracic limb. No bony connection exists between the scapula and the axial skeleton.






2. A joint motion whereby the distal end of an extremity moves in a circle.






3. The long bone of the thigh region; it forms the hip joint with the pelvis at its proximal end and the stifle joint with the tibia at its distal end.






4. The 'horn core' of horned animals; a process of the frontal bone. The hollow cavity within this process is continuous with the frontal sinus (the paranasal sinus of the frontal bone).






5. Bones formed in the soft organs (viscera); examples include the os penis - the os cordis - and the os rostri.






6. The front limb.






7. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






8. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






9. The vertebrae of the pelvic region; fuse to form a solid structure which forms a joint with the ilium called the sacroiliac joint.






10. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






11. The bones of the limbs (appendages)






12. The joint movement whereby an extremity is moved toward the median plane.






13. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






14. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


15. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






16. The joint movement that increases the angle between the two bones.






17. The hind limb.






18. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






19. A lateral - projecting process of a vertebra.






20. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






21. A bone of the sternum.






22. The joint composed of the carpal bones; referred to as the 'knee' of the horse and the 'wrist' of humans.






23. The most proximal bony structure of the pelvic limb; also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.






24. The 'forearm' region of the thoracic limb.






25. One of the irregular bones of the spinal column.






26. A pair of large holes in the pelvis located on either side of the pubic symphysis; the role seems to be to lighten the pelvis because no large nerves or vessels pass through them.






27. The soft material that fills the spaces inside the bones; two types of bone marrow are red bone marrow - which forms blood cells - and yellow bone marrow - which consists primarily of adipose tissue.






28. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






29. Secondary areas of growth in bones developing by the endochondral method; areas of bone development located outside the main portions of the carilaginous bone templates in a developing fetus.






30. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.






31. One of the three ossicles in the middle ear; also called the hammer - this bone is the outermost of the three ossicles and is attached to the tympanic membrane.






32. Rib whose costal cartilage directly joins the sternum.






33. A joint in which the bones are united by cartilage; also called an amphiarthrosis. Only a slight rocking motion is permitted between the bones.






34. The concave articular surface of the scapula; the socket portion of the ball - and - socket shoulder joint.






35. A thin bone located beside the tibia in the lower leg region of the pelvic limb. It is a complete bone in the dog and cat - but only the proximal and distal ends are present in horses and cattle. It doesn't support any appreciable weight - but acts a






36. A skull bone that is one of the internal bones of the cranium; forms the floor of the cranium and contains the pituitary fossa - a depressin that houses the pituitary gland.






37. Bones of the forelimb that lie between the carpals and phalanges of quadrupeds.






38. The cranial portion of the dorsal body cavity formed from several skull bones; it houses and protects the brain.






39. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.






40. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






41. A ball - and - socket joint - such as the shoulder or hip joint. Capable of all synovial joint motions.






42. The joint between the femur and the tibia; called the knee joint in humans.






43. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






44. One of the two bones (with the ulna) that form the antebrachium - or forearm; usually the main weightbearing bone.






45. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






46. A joint whereby one surface swivels around another like a door hinge; also called a ginglymus joint. The only movements possible are flexion and extension; the elbow is an example.






47. The group of vertebrae located dorsal to the thoracic region; noted for their tall dorsal spinous processes.






48. The last - most caudal sternebra; the _____ process.






49. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






50. Long bones of the axial skeleton that form the lateral walls of the thorax; dorsal portions are made of bone and form synovial joints with the thoracic vertebrae. Ventral portions are cartilage.
